JP Auclair Street Segment (from All.I.Can.) from Sherpas Cinema on Vimeo.
I grew up here. The multiple stair sets are in West Trail. The town is built up onto the side of the hill with narrow switchback streets which are NO JOKE in the winter (I used to deliver chinese food up there). I've shredded sections of this on my bike, but would never think to do it on skis.
